Wiring module

Abstract

A wiring module to be attached to a plurality of power storage devices arranged in an arrangement direction, the wiring module including: an insulating protector; and a flexible printed wiring board disposed in the protector, wherein the protector has a shape extending in the arrangement direction, the flexible printed wiring board includes a main body part extending in the arrangement direction and disposed in the protector, and an extension piece extending from the main body part, the extension piece has a curved portion that is curved, and the extension piece is inverted by the curved portion, and the protector includes a locking part that locks to the extension piece from a direction to prevent the curved portion from deforming back to an original shape thereof.

1 . A wiring module to be attached to a plurality of power storage devices arranged in an arrangement direction, the wiring module comprising:
 an insulating protector; and   a flexible printed wiring board disposed in the protector,   wherein the protector has a shape extending in the arrangement direction,   the flexible printed wiring board includes a main body part extending in the arrangement direction and disposed in the protector, and an extension piece extending from the main body part,   the extension piece has a curved portion that is curved, and the extension piece is inverted by the curved portion, and   the protector includes a locking part that locks to the extension piece from a direction to prevent the curved portion from deforming back to an original shape thereof.   
     
     
         2 . The wiring module according to  claim 1 ,
 wherein the protector includes a placement part on which the main body part is disposed,   the locking part protrudes, from a distal end of a column part protruding from the placement part, in a direction intersecting a direction in which the column part extends, and   the locking part locks to the extension piece from a side opposite to the placement part.   
     
     
         3 . The wiring module according to  claim 2 ,
 wherein an interval between the locking part and the placement part is set to be larger than the thickness of the extension piece.   
     
     
         4 . The wiring module according to  claim 1 ,
 wherein the extension piece and the main body part are coupled to each other via a proximal end portion, and   the main body part includes a cut-out portion extending from the proximal end portion in the arrangement direction, and from which the extension piece is cut out.   
     
     
         5 . The wiring module according to  claim 1 ,
 wherein the extension piece extends outward relative to a contour of the main body part.   
     
     
         6 . The wiring module according to  claim 1 ,
 wherein a detection unit that detects the state of at least one of the plurality of power storage devices is connected to a distal end portion of the extension piece, and the distal end portion of the extension piece is pressed against the at least one of the plurality of power storage devices.   
     
     
         7 . The wiring module according to  claim 6 ,
 wherein the flexible printed wiring board has a first surface on which a conductive path is formed, and a second surface on which the conductive path is not formed, and   the detection unit is connected to the conductive path on the first surface of the extension piece.   
     
     
         8 . The wiring module according to  claim 7 ,
 wherein the second surface of the distal end portion of the extension piece is pressed against the power storage device.   
     
     
         9 . The wiring module according to  claim 1 ,
 wherein the wiring module is a vehicle wiring module that is to be used mounted in a vehicle.
